In general terms, which way will require more server processing power and which way will return faster queries... if there is even a difference. The client's database is still on the dev MS SQL server but is essentially but the client has decided they want to collect two more fields of information. Both fields are going to be collection text data and probably varchar(300) will be sufficient for the column data types. Would it ultimately be more efficient to
Add two additional columns in the main table so the data is entered directly into each record, or Add an additional table (or two) with a foriegn key to the primary table that holds the info for each new field The SELECT statement for the main table could be modified to either add the new columns (a.NewColumn1 and a.NewColumn2) or it could contain nested SELECT statements that pull in the data from the other tables. Custom daisy-chained Insert or Update statements would be no problem and a cascade Delete relationship would take care of any deletions. I'm just trying to figure out which would be better from a performance standpoint?
I am working on asp.net 3.5 and in MVC using Linq to SQL classes. In my MVC project i am calling stored procedure using linq to sql that conatin query joining two tables.Below is my code in Partial class
[ Function(Name="dbo.GetUserWiseThreadDetail_SP")] [ResultType(typeof(Thread))] [ResultType(typeof(Reply))] public IMultipleResults GetUserWiseThreadDetail_SP([Parameter(DbType="VarChar(30)")] string userID) { ExecuteResult result = this.ExecuteMethodCall(this, (MethodInfo)(MethodInfo.GetCurrentMethod())), userID); return ((IMultipleResults)(result.ReturnValue)); }
In one of the controller i have made one more class
public class MypostIndexData { public IEnumerable<Thread> Thrds { get; set; } public IEnumerable<Reply> Repls { get; set; } public MypostIndexData(IEnumerable<Thread> thrds,IEnumerable<Reply> repls) { this.Thrds=thrds;this.Repls=repls; } }
finally coding of controller action method
ForumDataContext pmforum = new PMForumDataContext(); public ActionResult MyPosts(string userId) { IEnumerable<Thread>thrds; IEnumerable<Reply>repls; IMultipleResults result = pmforum.GetUserWiseThreadDetail_SP(userId); (this satement doesnot give any result,if i execute stored proc in sql it give the results) thrds = result.GetResult<Thread>(); List<Thread> thrdlist = new List<Thread>(thrds); repls = result.GetResult<Reply>(); List<Reply> replylist; if (repls != null) { replylist = new List<Reply>(repls); } return View(new MypostIndexData(thrds,repls));
I am unable to understand why i am not getting any results?
I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).
anyone know that can we used select statement to called queries table in database or not?usually people used select statement to called common table in database.
I am building a page that displays a product's details, with the information being called from an MSSQL database.I would like to be able to have a variable number of features listed for each product, so for example, Product A has a list of 3 features, Product B has a list of 7 features, Product C has 2 features listed etc.I would like to avoid having a lot of NULLS in my database, and would prefer not to restrict the number of possible features listed.Is there a common way to tackle this problem? Is it simply a case of setting up a table just to store features?
everytime I modify an SQLdatasource using VS wizards, I have to dettach the mdf in VS's server exporer, then hit refresh in the browser, then get the applicaiton is offline error message please remove some pia file, but i usually just count to 12 and then hit refresh again and the page renders properlyhad scoured the forum on more than one ocasstiion, think it has something to do with the Admin rights within SQL, Ive tried the SQL server surface configuration tool, and add administrator stuff, but not sure if i should add (user to provision) something like the asp.net thing, or network services or ??also cant figure out where to view which administrators are actually on SQL server,
Not sure if this is for SQL or .net! I have 3 tables which looks like
table1 ID Name 1 Jon
and
table2 ID Number Job 1 1 IT 2 1 Web 3 1 Admin
table1 ID ContractType 1 Temp 1 Perm
An inner join makes one table with 3 rows (I excluding the ID from table 2 for the join) which is saved as a view
viewTable ID Name Number Job ContractType 1 Jon 1 IT Temp 2 Jon 1 Web Temp 3 Jon 1 Admin Temp 4 Jon 1 IT Perm 5 Jon 1 Web Perm 6 Jon 1 Admin Perm
I want to display these results on a web page via the grid view. However, I don't want to show the user 6 times! I want to show the user name once, the contract type once and each Job! What is the best way to do this? Is there a fault with the database design already? I assume the easiest answer is to not join them in a view but query each section 3 times from the website but I'd rather 1 connection only!
I have a table in my aspnet database. I added a bottom row "Not Selected", if the user doesn't select from a databound drop down list. This row is at the bottom, because I just added it to the table data. Is there any way to move this one row to the top of the table manually? There is not "cut" and "paste" when I select the whole row.
I am working on a multi-lingual application Assume the following:
Database has 50 tables and application has to support 5 languages
Which is the best way to design the database:
1. Include a langugae column for each table. Repeat the values for each language. Say i have a country table which has 100 countries in it. Then my design will contain 500 rows (100 for each langugae)
2. Create a separate table which will contain the translations for all the 50 tables in with a foreign key to the parent table.
I'm completely new to both VB.NET and JSON, and I'm trying to figure out how to do SQL queries towards an SQL 2005 Express server and format the return value to JSON. I got the queries working using this (perhaps very newbie-like) code;
Imports System Imports System.Data Imports System.Data.SqlClient Imports System.Web.UI Imports System.Web.UI.WebControls Partial Public Class SQLConnect Inherits System.Web.UI.Page 'Defines SQL variables Dim con As New SqlConnection Dim cmd As New SqlCommand Dim dr As SqlDataReader Dim ReadData As String Dim i As Integer Sub Click(ByVal s As Object, ByVal e As EventArgs) 'Define SQL address, database, username and password con.ConnectionString = "Data Source=localhostSQLEXPRESS;Initial Catalog=tempdb;User ID=tesst;Password=test" Try 'Initialize connection con.Open() 'Specify SQL query cmd = New SqlCommand("SELECT * FROM Member", con) 'Execute query, dump result array into variable dr = cmd.ExecuteReader() messageLabel.Text = "<br />Connection established<br />" While (dr.Read) i = 0 For i = 0 To dr.FieldCount - 1 'Dump query results into a variable ReadData += dr.Item(i).ToString Next End While 'Print query results messageLabel2.Text = ReadData 'Close connection con.Close() Catch ex As Exception messageLabel.Text = "<br />Connection failed<br />" End Try End Sub End Class
I have been looking at this, and I would love to see some code examples using this class or any other good method.
SELECT 1000000*QuantityNC/Quantity AS PPM FROM [table1] However I need my WHERE clause to do thisI need the above calculation depending on BusUnit, which is linked to PartNumber, which is in the above table. also it has to be by Company (which is selected from a dropdown). And also based on the current month and year.
PartNumber and CompanyName are in [table1] BusUnitID, PartNumber, SupplierID, are in tblParts BusUnitID and BusUnit are in tblBusUnits

I what to display the value on the same line instead of the 2 1st values. How can i store the 2 colums wich lot of SQL values on my vb.net script and diplay the result with the other data from the SQL query ?
I need to somehow test if a table exists in a database. If it does not then I need to create the table. How can I test for existence of a table using SQL? It seems like some type of SQL logic is needed?
I need to select a field value from a database table. If the value read is '1' then I need a 'Y' to display as output in the select statement. I haven't figured out how to do this yet and queries I tried that did not work.
select IsIata from Table_1 CASE WHEN (IsIata = '1') THEN 'Y' select IsIata CASE WHEN (IsIata = '1') THEN 'Y' from Table_1
I get an error when I try to update a row in an SQL database table with a string of fewer characters than were previously stored. I attempted to correct this problem by using the "PadRight" function in my C# webpage event handler to fill in the remaining characters with spaces, but I don't seem to be able to make that work. So, what do I do when I want to store fewer characters in a table row that has more characters previously stored in it?
